Building a 9" Ford Rear - What Width?

[68ZClone]

What width rear end are most of you running in your cars? I'm modifying my 68 Camaro for street and some autocrossing. This will include the DSE mini-tubs. I've got most of the materials for a 9" Ford rearend and am curious if most of you are running stock width or narrowed. I know it ultimately depends on the wheel backspacing you want to run, wheel width, etc. But where are most of you starting out?
